Recently I acquired this scissors (shears ?), original except for soft marks of rust, the cut thread is original of factory, total size of 10 inches, logo mark of J.A. Henckels from 1900 up to 1969, doesn't have special finish, original marks of emery and polishing. I have as curiosity to know if some exists factory catalog, book or site, available for consultation of images and description on scissors. Any help will be well coming. Thank you in advance.
